SPECIFICATION forming part of Letters Patent No. 715,791, dated December16, 1902.

Application iile. July 14, 1902. Serial No. l1 5,579. (No model.)

To @ZZ whom, t wea/y concern.-

Be it known that I, WILLIAM C. HAPPE, a citizen of the United States,residing at Davenport, in the county of Scott, State of Iowa, haveinvented certain new and useful Improvements in Railroad Trucks; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to railways; and it has for its object to providearailway in which the rails will be elevated and upon which the carswill be held securely against displacement when traveling at enormousspeed.

A further object of the invention is to provide a construction whichwill permit of use of lighter cars than is customary.

An additional object of the invention is to provide an arrangement forholding the cars upon the track which is adjustable and may be adjustedat both sides of the cars from a single point upon the car, otherobjects and advantages of the invention being understood from thefollowing description.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the severalviews,Figure 1 is a transverse section through a trackway embodying thepresent invention and a car thereon, portions being shown in elevation.Fig. 2 is a side elevation of a portion ofa trailer-car and illustratingthe arrangement of the wheels at one side of the truck. Fig. 3 is a Viewsimilar to Fig. 2 and showing a double truck such as is used upon themotor-car. Fig. 4 is an end elevation of a truck. Fig. 5 is a section online 5 5 of Fig. 2 and showing the sliding arrangement of the upperwheelat one side of the truck. Fig. 6 is an elevation of the screw atone end of the truck which adjusts the upper wheel. Fig. 7 is a planView of the mechanism for adjusting all of the screws of the trucksimultaneously. Fig. 8 is an elevation of one of the tension-screws.Fig. 9 is an end elevation of a motor-car and illustrating the truck andthe arrangement of the parts for varying the tensions of the springsthat hold the upper wheels against the angular rails.

Referring now to'the drawings, the present trackway comprises aplurality of pairs of upwardly-con verging posts 10 and 11, which arepreferably of skeleton formation, as shown, the lower ends of which aresecured to and rest upon the foundations or bases 12 and 13 and areconnected at their lower ends by the strut 14, there being also ties 15and 16, which ext-end diagonally from the lower ends of the posts to theupper portions of the opposite posts. Secured to the posts of each pairis a cross-beam 17, on which are mounted a pair of beams 18 and 19,which support rails 20 and 21, the beams 18 and 19 being connected by asuitable number of ties 22. Upon the upper ends of the posts andextending longitudinally of the trackway are the angleirons 23, uponwhich are secured the channelirons 24, one flange 25, which is the innerflange of each channel-iron, receiving between it and the flange 26 ofthe corresponding angle-iron one flange of an angle-iron 27, the severalflanges being riveted together, as shown. The angle-irons 23 are in factupper rails and are engaged on their under faces by the upper wheels ofthe car-trucks hereinafter described. The trucks of the cars that travelupon this trackway have lower supporting-wheels 30, that run upon therails and 2l, and have also upper wheels 50, that run against the underfaces of the upper rails and prevent the wheels 30 from leaving thelower rails. The passenger-cars have their trucks provided with oneupper wheel at each side, as shown in Fig. 2, while the motor-car hastwo upper wheels at each side of the truck, as shown in Fig. 3.

In Fig. 2 ofthe drawings there is shown the truck for passen ger-cars,while in Fig. 3 there is shown a truck for a motor-car, Figs. 4 and 6having also reference to the motor-car, as well as Figs. 7 and 8. Thebolster 30 of the truck is disposed upon the longitudinal beams 31',having boxes 32, in which turn the ends of the axle 33, that carries thewheels 30, that run on the rails 2O and 21. Upon the upper face of thebolster 30 is mounted the U- shaped frame 35, the ends 36 and`37 ofwhich are passed upwardly at the sides of the body of the car 38 and areslidably engaged with die-plates 39, which latter are secured to thesides of the car-body. The truck is thus held against movementlongitudinally of the carbody and the car-body is permitted to have IOOvertical movement with respect to the truckbolster, the body beingsustained by the helical springs 40, which rest with their lower endsupon the frame 35, while upon their upper ends rest the longitudinalsills 4l of the car-body.

Upon the sides of the car-body at opposite sides of each of the plates39 are secured dieplates 42 and 43, in which are slidably mounted plates44 and 45, having other plates 46 and 47 slidably mounted therein forvertical movement, and these last-named plates have openingstherethrough, through which are passed the axles 49 of wheels 50. Theaxles 49 are mounted in bearings 51 on body-bolsters 52. Passed throughthe body-holsters 52 and through the corners of the truckframes 53 arebolts 54, the lower portions of which directly above the truck-frame arethreaded, and with the threaded portions are engaged nuts 55, havinggear-teeth on their outer faces, so that they are in effect pinions. Onthe bolts 54 and resting with their ends, respectively, against thebolsters 52 and the pinions 55 are helical springs 56, which sustain thebolsters 52 and therewith the aXle 49 and its wheels 50.

Mounted upon the truck are the shafts 57 and 5S, each having a pair ofworms 59, and each of these worms engages a pinion 55. The shafts 57 and58 carry bevel-gears 60 and 61, which mesh with similar gears 62 and 63on a transverse shaft 64, having also a pinion 65. A vertical shaft 66is mounted on the front platform of the car, and xed to its upper end isa hand-wheel 67, which is located convenient to the motorman. The shaft66 carries a worm 68, which meshes with the pinion 65, and thus when thehandwhcel is rotated the shafts 57 and 58 will be actuated to turn thepinions 55 in corresponding direction, so that they will be fed upwardlyor downwardly of the bolts. As the pinions feed upwardly the tensions ofthe springs 56 are increased and the wheels 50 are pressed upwardly withincreased force. The wheels 50 are arranged to run against the lowersides of the angular upper trackrails and prevent the truck from risinga distance sufficient to cause the wheels to leave the track-rails 2Oand 2l.

In Figs. 2 and 5 is shown the arrangement of truck for passenger-cars,wherein there is only one upper wheel at each side of the truck. Thepassenger-car is also shown in Fig. l of the drawings. Referring now toFig. 2, the car-body 70 has a die-plate 7l fixed thereto, in which isslidably engaged an arm 72 of a U-shaped plate similar to the plate orfram'e 35, it being understood that there is a die-plate 7l at each sideof the passenger-car, the U-shaped plate or frame being mounted directlyupon the truck-bolster 73 and there being helical spring 40 between theweb of the U-shaped frame and the sills on the bottom of the car-body tosustain the car-body yieldably. 'In the end portions 72 of the U-shapedframe are slidably mounted plates 74, having stub-shafts 75, which carrywheels 76, which run against the under side of the angular upper railsof the traokway. Helical springs 77 are disposed upon the bolster 73 andsustain the plates 74 yieldably. With this construction it will be seenthat the upper wheels prevent the lower wheels from rising from thetrack on which they run, the play of the plates 74 vertically being lessthan the depths of the flanges of the lower wheels, so that the lowerwheels cannot rise sufficiently far to permit their fianges to pass overthe rails.
